All arithmetic is performed modulo 2^n, where n is the number of bits in the type.; For coercing between any two integer types, use fromIntegral, which is specialized for all the common cases so should be fast enough.

The first method uses the new stoi() method that came with the c++11 update that ma Haskell-style. A baked-in notion of type classes in the overall style of Haskell, Purescript, Idris, etc. Lawful. First-class laws for type classes, which are enforced by the compiler. Hierarchical.

For rounding see Algebra.RealRing. I think that the RealIntegral superclass is too restrictive.

Clash "erroneously" translates Haskell's Integer to 64-bit signed number; even when the context demands more. Properly translating Integer has proven non-trivial, so there's no easy path forward; outright banning Integer in Clash designs

Haskell uses deferred execution, or, thunking, to perform lazy computations. In working with large data structures, such as lists of an arbitrary length, thunks may accumulate in memory. Suppose we’re summing a list of 10 million elements; in the lazy evaluation model, a thunk will have accumulated 10 million deferred + operations, ready for evaluation, but it cannot happen until all

Properly translating Integer has proven non-trivial, so there's no easy path forward; outright banning Integer in Clash designs I am trying to calculate the length of an Integer in Haskell, using the fact that the length is equal to truncate (log10(x)+1). Using Integers I created: len :: Integer -> Integer len i = toInteger (truncate (logBase 10 (fromIntegral i)) + 1) Unfortunately, not all numbers get the correct length.

tointeger (6) Overuse of fromIntegral in Haskell . Whenever I write a function using doubles and integers, I find this problem where I am constantly having to use 'fromIntegral' everywhere in my function. For example: import Data.List

Next, you usually use camelCase instead of snake_case in names in Haskell and hide the functionality in local bindings if you don't want to reuse functions, e.g. min_decoding :: String -> Integer min_decoding word = base_conversion (toInteger . length . nub $ number) $ catMaybes number where number = fix_decoding $ min_aux word Map.empty 0 min_aux =

The default value is integer-gmp, which uses the GNU Multiple Precision Arithmetic Library (GMP) to define the Integer type and its operations.

For rounding see Algebra.RealRing. I think that the RealIntegral superclass is too restrictive. Non-negative numbers are not a ring, but can be easily converted to Integers.
